QUESTION: What are the functional differences between people with greater
trochanteric pain syndrome (GT), hip osteoarthritis (OA) or an asymptomatic
population as measured by walking, Time Up and Go, single leg standing and strength ? DESIGN: Cross sectional study with blinded measurers. PARTICIPANTS: 38
participants with GT, 20 with end stage hip OA and 21 asymptomatic healthy
control (AS) participants.
All participants were women. OUTCOME MEASURES: Pain
(numeric rating scale), Walking speed (m/s), cadence (steps/min) and step length
(m) measured via the 10m walk test and the Timed Up and Go; balance via single
leg stance (s) duration; and hip abduction, adduction, medial and lateral
rotation strength, standardized to body mass (BM) via the body mass average index
(BMavg), measured via a wall mounted dynamometer. RESULTS: The two symptomatic
groups reported similar pain levels (p=0.226), more pain then the AS group
(p<0.000). Compared to the AS participants, participants with GT or hip OA
demonstrated lower walking speed (10mwt and TUG, p<0.001), lower cadence and
shorter duration single leg stance on the affected leg (p<0.05). Participants
with GT or hip OA also demonstrated bilaterally weaker hip abduction than the AS
group (p</=0.005). Compared to AS and GT participants, participants with hip OA
demonstrated adduction weakness on the affected side (p=0.008 and p=0.002
respectively). CONCLUSION: There is a significant level of dysfunction and
impairments associated with GT and hip OA. As activity limitations do not appear
to be differentiated by structural impairments, we suggest that pain, rather than
the underlying pathology may be the driving impairment that leads to walking and
single leg standing dysfunction.
